Emotiva XPA-1 - Manual (Page 15)

XPA‐2 Back Panel
1. Remote Trigger Input ‐ The XPA‐2 can be remotely triggered by another device. When a remote trigger output from a
preamplifier, processor or other audio device is connected to the trigger input here, the amplifier will power up and shut
down along with the first device.
A 3.5mm, 5‐12 volt mono audio cable is used for both inputs and outputs. If building your own cable, center is positive and
outer shield is negative.
2. Working LED Selector – The two ‘On’ status LEDs (one for each channel) on the amplifier faceplate can be turned on and
off with this selector.
3. Meter LED Selector – The meter LEDs (which move in sync with amplifier output) can be turned on and off with this
selector.
4. Right Channel XLR/Balanced Input – Connects with an XLR/Balanced cable to the right channel output of a preamplifier or
processor.
5. Right Channel Balanced/Unbalanced Input Selector – When turned towards ‘Un‐Bal’, the RCA (unbalanced) input is
chosen and active. When turned towards ‘Bal’, the XLR/Balanced input is chosen and active.
6. Right Channel RCA /Unbalanced Input ‐ Connects with an RCA/Unbalanced cable to the right channel output of a
preamplifier or processor.
7. Bridged Configuration Selector – Leaving this selector on ‘OFF’ keeps the XPA‐2 in standard two channel mode. Turning it
to ‘ON” bridges the two separate channels into one, turning the XPA‐2 into a monoblock amplifier. NOTE: Bridged mode is
meant for use with 8 ohm speakers. Using bridged mode with lower impedence speakers may cause overheating, causing
the amplifier to go into protect mode (fault), and possibly sustain permanent damage.
8. Left Channel RCA /Unbalanced Input ‐ Connects with an RCA/Unbalanced cable to the left channel output of a
preamplifier or processor.
9. Left Channel Balanced/Unbalanced Input Selector – When turned towards ‘Un‐Bal’, the RCA (unbalanced) input is chosen
and active. When turned towards ‘Bal’, the XLR/Balanced input is chosen and active.
